Apt Operations

Manage apt packages and repositories.

apt.deb

Add/remove .deb file packages.

apt.deb(src, present=True, force=False)

• src: filename or URL of the .deb file
• present: whether or not the package should exist on the system
• force: whether to force the package install by passing –force-yes to apt

Note:

When installing, apt-get install -f will be run to install any unmet dependencies.

URL sources with present=False:

If the .deb file isn’t downloaded, pyinfra can’t remove any existing package as the file won’t exist until mid-deploy.

Example:

# Note: Assumes wget is installed.
apt.deb(
    name='Install Chrome via deb',
    src='https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb',
)

apt.key

Add apt gpg keys with apt-key.

apt.key(src=None, keyserver=None, keyid=None)

• src: filename or URL
• keyserver: URL of keyserver to fetch key from
• keyid: key ID or list of key IDs when using keyserver

keyserver/id:

These must be provided together.

Examples:

# Note: If using URL, wget is assumed to be installed.
apt.key(
    name='Add the Docker apt gpg key',
    src='https://download.docker.com/linux/ubuntu/gpg',
)

apt.key(
    name='Install VirtualBox key',
    src='https://www.virtualbox.org/download/oracle_vbox_2016.asc',
)

apt.packages

Install/remove/update packages & update apt.

apt.packages(
    packages=None, present=True, latest=False, update=False, cache_time=None, upgrade=False,
    force=False, no_recommends=False, allow_downgrades=False, extra_install_args=None,
    extra_uninstall_args=None,
)

• packages: list of packages to ensure
• present: whether the packages should be installed
• latest: whether to upgrade packages without a specified version
• update: run apt update before installing packages
• cache_time: when used with update, cache for this many seconds
• upgrade: run apt upgrade before installing packages
• force: whether to force package installs by passing –force-yes to apt
• no_recommends: don’t install recommended packages
• allow_downgrades: allow downgrading packages with version (–allow-downgrades)
• extra_install_args: additional arguments to the apt install command
• extra_uninstall_args: additional arguments to the apt uninstall command

Versions:

Package versions can be pinned like apt: <pkg>=<version>

Cache time:

When cache_time is set the /var/lib/apt/periodic/update-success-stamp file is touched upon successful update. Some distros already do this (Ubuntu), but others simply leave the periodic directory empty (Debian).

Examples:

# Update package list and install packages
apt.packages(
    name='Install Asterisk and Vim',
    packages=['asterisk', 'vim'],
    update=True,
)

# Install the latest versions of packages (always check)
apt.packages(
    name='Install latest Vim',
    packages=['vim'],
    latest=True,
)

# Note: host.fact.os_version is the same as `uname -r` (ex: '4.15.0-72-generic')
apt.packages(
    name='Install kernel headers',
    packages=['linux-headers-{}'.format(host.fact.os_version)],
    update=True,
)

apt.ppa

Add/remove Ubuntu ppa repositories.

apt.ppa(src, present=True)

• src: the PPA name (full ppa:user/repo format)
• present: whether it should exist

Note:

requires apt-add-repository on the remote host

Example:

# Note: Assumes software-properties-common is installed.
apt.ppa(
    name='Add the Bitcoin ppa',
    src='ppa:bitcoin/bitcoin',
)

apt.repo

Add/remove apt repositories.

apt.repo(src, present=True, filename=None)

• src: apt source string eg deb http://X hardy main
• present: whether the repo should exist on the system
• filename: optional filename to use /etc/apt/sources.list.d/<filename>.list. By default uses /etc/apt/sources.list.

Example:

apt.repo(
    name='Install VirtualBox repo',
    src='deb https://download.virtualbox.org/virtualbox/debian bionic contrib',
)

apt.update

Updates apt repositories.

apt.update(cache_time=None, touch_periodic=False)

• cache_time: cache updates for this many seconds
• touch_periodic: touch /var/lib/apt/periodic/update-success-stamp after update

Example:

apt.update(
    name='Update apt repositories',
    cache_time=3600,
)

apt.upgrade

Upgrades all apt packages.

apt.upgrade()

Example:

apt.upgrade(
    name='Upgrade apt packages',
)
